which is also the handle, a nozzle and means intermediate the contalner and nozzle for metering liquid from the container through the nozzle at a rate proportionate to the rate of movement of the instrument over the surface to be striped.

A further object of the invention is to provide a striping instrument having a nozzle and means positioned therein for supporting the discharge end of the nozzle in spaced relation to the surface to be striped.

A still further object of the invention is to provide a striping instrument having a nozzle and means positioned therein for spreading the liquid discharged therefrom.

Yet a further object of the invention is to provide a striping instrument having a nozzle with means positioned therein for controlling the flow of liquid through the nozzle to the discharge end thereof, so that a portion of the liquid discharged will be spread the maximum width of the stripe and the remaining portion deposited in the line of travel as a filler.

Still a further object of the invention is to provide a striping instrument which has the advantages of spreading a stripe of uniform thickness and width, is highly efiicient in operation and yet of marked simplicity as a whole and in respect to each of its component parts, so that its manufacturing is economically facilitated both as regards parts and their assembly.

Other objects of the invention will appear from the following description taken in con Serial N0. 320,?71.

Referring to the drawings for more specific details of the invention, 10 represents the body of the instrument. As shown, the body comprises a cylindrical hollow member closed at one end and open at the other. The closed end has threaded therein a container 11 and a handle 12. vVhen assembled, as shown in Figs. 1 and 2, theaxis of the handle is in the axis of the body and the container is at an angle to the body. The handle and container are assembled or arranged. in this man ner when the instrument is to be used on a vertical or substantially vertical surface, but when it is to be used on a flat or substantially flat surface, the container is substituted for the handle as shown in Fig. 3. hen thus assembled, the container is also the handle and the aperture in the wall of the body from which the container has been removedis closed by a plug 13.

The open end of the body has threaded thereon a cap 14 provided with an inturned flange 15 and positioned in the cap 14 is a bearing sleeve 16. The sleeve 16 has a circumferential flange 17 which engages the inner face of the flange 15 and a double diameter bore 18 in which is positioned for rotation a hollow shaft 19. This shaft has formed on one end a disk or roller 20, the periphery of which is suitably knurled and the other end of the shaft has formed thereon a key 21, the object of which will hereinafter appear.

The shaft also has formed thereon in spaced relation to the roller 20 and with respect to each other circumferential flanges 22 and 23 and positioned on the shaft between the roller 20 and the flange 23 are roller bearings 24 or other suitable bearings may be employed.

The sleeve 16 has a circumferential groove 25 in which is positioned a slot 26 and a key 27 is fitted in the slot to engage the channel between the flanges 22 and 23, the key being secured in position by a split ring 28 fitted in the groove. This structure provides suitable means for retaining the shaft in the sleeve 16 and permits free rotation thereof.

Supported on the end of the sleeve 16 within the cap 14 is a disk 29 and a pin 30 projects from a disk 33 and extends into an aperture in the disk 29 to prevent relative rotation thereof. The disk 29 has positioned therein a pump 31, one of the gears of which is centrally bored to register with the bore in the shaft and this gear is notched as indicated at 32 to receive the key 21 on the end of the shaft.

The disk 33 rests on the disk 29 over the ,pump 31 and is also secured to the disk 29 by the pin 30. This disk has a passage 34 registering with the intake of the pump, a passage 35 registering with the outlet of the pump and a central bore 36 registering with the bore in the shaft. The surface around the bore 36 is beveled or recessed as indicated at 37 and the passage 35 leads to this recess.

A nozzle 38 is fitted in the bore of the shaft 19. The nozzle has an axial bore 39, a radial bore and a peripheral flange 41. The

.fla'nge 41 is formed upon the shank of the nozzle and rests upon the disk 33. The flange is sufficiently large to cover the recess 37 and the radial bore 40 communicates with the recess 37 which in turn communicates with the passage 35 leading from the outlet of the pump.

The nozzle and the disks 29 and 33 are retained in position by a plate 42 resting on the flange 41 and bearing against the end of the wall of the body 10, these parts being clamped in fixed position by the cap 14 when screwed on the body 10. The plate 42 has a plurality of apertures 43 providing a communication between the body 10 and a restricted or auxiliary chamber 44 between the plates or disks 42 and 33. This chamber communicates with the passage 34 leading to the intake of the pump.

The bore in the nozzle is enlarged at the discharge end as indicated at 45 and the increased diameter provides a shoulder 46. A plug 47 has a press fit in the end of the nozzle and the inner end of the plug engages the shoulder. The plug is provided in its periphery with a plurality of equally spaced longitudinal grooves 48 which extend from the point of the plug to the butt thereof and communicate with the axial bore 39. The point of the plug extends slightly beyond the nozzle and is rounded as indicated at 49, so that in manipulating the instrument over a surface it will glide smoothly and will not scratch, drag or cause vibration of the instrument tending to produce an uneven or irregular stripe.

The point of the plug serves to support the discharge end of the nozzle in spaced relation to the surface to be striped and to distribute or spread the liquid as it is delivered through the grooves therein. The grooves are so positioned that a portion of the liquid is spread the maximum width of the stripe and the remaining portion fills in the track of the point.

A modified form of the plug is shown in Figs. 10, 11 and 12. In this modification, the plug is made somewhat shorter and the outer end thereof is formed with a stem 50 terminating in a ball 51. The ball is positioned with its diameter in the axis of the nozzle and in spaced relation to the discharge end thereof, so that it will spread the liquid fed through the nozzle to agreater extent than the point illustrated in Figs. 7, 8 and 9.

A further modified form of the plug is shown in Figs. 13, 14 and 15. In this modification, the plug has formed thereon a short projection 52 positioned with its axis in the axis of the plug and provided with a rounded end as at 53. The diameter of the projection is relatively small, so that there will be but little tendency to spread the liquid fed through the nozzle, yet it is sufficiently stout to support the discharge end of the nozzle in spaced relation to the surface to be striped in order that the flow of liquid through the nozzle will not be interrupted.

The roller 20 provides a guide for the instrument and an actuator for the pump driving mechanism. \Vhen the instrument is moved in contact with the surface to be striped, with the roller in contact with a molding or wall, rotation is imparted to the shaft 19 which in turn rotates the gear 31. Liquid flows by gravity into the chamber 44 through the apertures 43 in the plate 42 and is drawn into the pump through the passage 34. From the pump, the liquid is forced under pressure through the passage 35 into the annular recesses 37 formed between the beveled surface of the disk 33 and the flange 41 of the nozzle, and from such recess the fluid moves through the bore 30 into and through the bore 89 in the nozzle.

Although this invention has been described in connection with certain specific embodiments, the principles involved are susceptible of numerous other applications that will readily occur to persons skilled in the art.
